Be it known that I, ELIAs-IH. KEITH, of the city and county of Peoria, and StateofIllinois, have. invented a new and useful apparatus for Coupling Cars; I do hereby declare that the followingisa full, `cliear,`ind exact description'ot` the construction and operation of the same, reference being had to the annoxed'drawings braking i a part of this specication, in which- Figure 1, the apparatus before being` coupled.

Figure 2 is the apparatus coupled. Figure 3, longitudinal elevation. Figur-e4, perspectivcview. Figure 5, plan and elevation of bumper. 4Figure 6, perspective of loop.L i Figure 7,. perspective of hook andrai-m. Figur e 8, diagrain of -h'ooki g g Y p i l My apparatus consists of a bumping iron, A, six inches deep by ten inches wide, and projecting from car say fifteen inches, provided with a ring or loop, B,' having `two arms, g g, bentso as to form nearly a right angle with the plane of loop, made of lwrought iron, sayone and a half inches thick by two `inches wide; thc width, being in -the'- plane of the loop, (for strength,) o r presenting its thinnest appear-anse edgways of loop or perpenf; dicular.- rTh'e arms, g g, of the loop, B, are curved slightly backwards from centre o f loop, thesize pr diameter` of'` ring or loop, B, say fourteen inches, and the aifms each about eight inches longthrough the arms neartlxex` bend are bolt holes, It, say one in'ch in diarneter through which the loop is attached tobump'er, vthe loop standsf- 'with the plane of its ring nearly parallel'with the side of the bumper. One arm resting .on-upper, and the other on the under. surface of bumper. On this bolt, the loopv freely turns, though its `motion is checked at certain distances by the stops, z' 7c, cast in the burper` A. revolvinghnbolt ending at one side ina hook, C, and having a crank, D, and rod, d, at. the other end runs through the bumper horizontally, sii: `inches in rear of loop,B, thc Y .hook being situatedV on the opposite side of bumperto the loop, andV the point of hook `projecting i'ivo inches from side of bumper as seen in drawing, the inner angle -of hookfalls back about one inch behindcentre or axis of bolt, the outer end, c, of hook turns slightly inwards towards bumper to prevent possible escape of loop,-

4 B, lthe hook of one and a half inch lwrought iron, it also has fitted-to it at-the part of bolt which passes through.

the mortise, in, the revolving bar,a,inv shape like the letter L, and fixed by one ofy its points to bolt and prevented from' turning on bolt bythe bolthaving a'attened surface at that part. p This reversing bar is made of 1 one inch iron, and'is two inches broad at thc bolt, and one and a halt' at the other, this bar is set` on bolt at a right angle to the hook, C, and stands perpendicularly when -the hooi: points forwaids orto head of bumper, and the outer arm lies horizontally en the bumperin the slotor morrtisefm, from centre of bolt or hook, C, toangle of reversing barf,a,is about four and a-half' inches and from thence to outer extremity of arm is seven inches, to give the reversing bar play, a rnortise is cast in Vthe, bumper extending through from upper to lower surfacef4 oneand a half V inch wide bytwelve inches in length, but not allowing the baito fall through at the end towards head'of burnpcr, where itis desired to be within range of ablow `fromthe armpg, of the loop, B, a crank, D,

, is, fitted on the.V opposite end of bolt, C, ofsuiiicien't V strength (with nut,) which stands nenrlytat a right angle with'hfook, C, and when .said hok points., to fore part of bmper,.(before coupling) has about one inch inclina?V tion forward Vtowardshead of bumper, so that with weight of rod, d, the hook may be retained in the proper position for coupling, z'e. readyfor reversing by blow .on end of reversing bar, a, thc crankrl), then falls back-` wards towards oar and then yhangs `nearly perpendicular, the.r veight of Yrod giving it an impetus" downward and retains thehook in proper position over loop B. The rod is carried to top.of freight ear, or to top railing on platform of passenger car,whcre the rod passes through a ring allowing it free play. Itis made of three-quarter inch iron. The face, d, to forward part'of-bumper in front of hook, C, is to guard hook from contact with loop, B, in approaching. The operation of this lapparatus is as follows; in fig; 1, thc bumper represented approaching the loop, B, being ready for catching on hook, C, the arm,- g, of loop projecting'in front of bum'per, receives a blow from the opposite bumper, which reverses the hook, C, over the loop which has just turned' into place. The

same operation simultaneously takes place with thc opposite bumper, `thus 'attaching both hooks and loops andl eecting a doublel coupling The red lines in fig. 1, sho'w the position of hooks as reversed on attachmentor` coupling. The coupling or attachment is` shown at g. .2. Thesehumping irons havo cai-ities for .the reception` of 'linkl and pin, in case Where it is necessary .to attach the h unzipelsV now in use. The'afivantage'off this` mode vof coupling isftho double attachment, so that if thl'e'coupling on one side hx'eakl Also che exemption from danger of lifeV and'limb in the operation. The breaksm'as presence between thecars at the bmpes being needless; I y I only in this'invention, thcre'also exhibitingl another advantage 'a fbut can liucoluphe them from I rod, d, raisestho crank,D, and reversee the hook, C.
